A snippet of the complaint:
After initial approval of the Canyon Mine, the Forest Service formally designated Red Butte and surrounding areas as a Traditional Cultural Property. This designation means Red Butte is eligible for inclusion in the National Register of Historic Places and meets the definition of a “historic property” under the National Historic Preservation Act (NHPA). The Forest Service also recognized that Red Butte is a sacred site to the Havasupai Tribe. The Forest Service’s 1986 approvals did not analyze the Canyon Mine’s potential effects to Red Butte as a historic property under the NHPA. The Forest Service recently commenced consultation with the Havasupai Tribe concerning the Canyon Mine’s impacts to Red Butte, and claims that it intends to continue consultation. The Forest Service is refusing to undertake and complete a NHPA Section 106 Process relating to adverse impacts to the Red Butte TCP, including consulting with the Tribe for the purposes of developing a Memorandum of Agreement, prior to allowing Canyon Mine to restart mining operations, as required under NHPA and its regulations, 16 U.S.C. § 470f, 36 C.F.R § 800.13(b)(1).
